Last week we investigated the ‘most popular’ medieval names for women, including a long discursus on why the scare quotes. All the same caveats hold when we turn to look at the men’s names: Without access to systematic data that counts individuals only once and provides the same level of coverage in every place and time, there is no way to say definitively what the most popular medieval given names were.
Unsurprisingly, the list of men’s names that I review on a daily basis because I can pretty much guarantee some editorial assistant has added new citations of is longer than the list of women’s name. And many of the names on it will strike few as surprising (though I personally find it interesting how they cluster into pairs or triples in terms of the letter they start with, and how weighted towards the end of the alphabet they are):
These names have remained enduringly popular, with all of them showing up in, e.g., the top 100 of the Top Names Over the Last 100 Years in the US (John: 2; Robert, 3; William, 5; Richard: 7; Charles, 9; Thomas, 10; Paul: 17; Jacob: 34; Henry: 52; Peter: 55; Walter, 57; Roger, 66; Philip, ; 94note that since this counts individual variant spellings, rather than combining all variants together, this list separates Jacob from James, which comes in at no. 1).
But others on the list may be more surprising — names that have fallen out of common use, or which while still familiar nowadays may not strike one as especially typical of the Middle Ages. These names are:
Of these, the two that I found the most surprising — the ones I hadn’t really realized were as popular as they are until we started compiling such a huge corpus — are Louis and Theodoric. Louis, from its early Latinized form Hludowicus to its modern forms such as Louis, Lewis, Lodovico, Ludwig, and Luis, was an amazingly productive name, showing up in all cultures touched by the Carolingian empire, and, later, France (there being more medieval French kings named Louis than any other name). The popularity of Theodoric can be traced back to Theoderic the Great, ruler of the Ostrogoths at the fall of the western Roman empire. His deeds entered legend, and his name spread across Europe, spawing many variants and diminutives: In fact, more distinct spellings of this name are recorded than any other name we have catalogued so far (and that includes John!). In French, it became T(h)ierry; in Dutch, Derek and Dirk; in High German, Dietrich; in Low German, Diderik. The range of diminutive forms includes examples that a non-expert would scoff at as related: Who would think that Thidemann, Dytlin, Dietz, Tile, Tous, Tijdeke, and Thierrion are all nicknames of the same name?
All of these entries are already quite diverse in the citations they include, but will only become more so in the future. Mark your calendars, we are one week away from the publication of the next edition (our final one of 2015)!
